For the low Mach number limit, it is known that excessive numerical error degrades both the solution and the convergence rate. In this study, such problems are fixed by controlling numerical dissipation contained in the pressure term of AUSM-family schemes. For the high Mach number limit, on the other hand, there are crucial problems remained unsolved at a shock front, such as the carbuncle phenomenon. It is shown that the stability strongly depends on the formulation of the mass flux function in AUSM-family schemes. The new scheme, named SD-SLAU (Shock Detecting SLAU), switches the pressure difference term in the mass flux scheme using a shock detecting function in a way that the new scheme can readily be applied to unstructured grids. This scheme provides proper amount of dissipation into both normal and tangential directions to the captured shock in our tests: In particular, numerical noises (\"wiggles\") behind the shock are eliminated.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064967051","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-10-012","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター"},{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Degital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"},{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Degital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"嶋, 英志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北村, 圭一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shima, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kitamura, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"64967051.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64967051.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4758/files/64967051.pdf"},"version_id":"a9799646-12bf-41c6-91c6-95b319829fb8"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"全速度数値流束スキームの改良について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"全速度数値流束スキームの改良について"}]},"item_type_id":"5","owner":"1","path":["925","1539","1883","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4758","relation_version_is_last":true,"title":["全速度数値流束スキームの改良について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:32:15.781172+00:00"}
